Arriving May 1, 2018

On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.

Chasing New Horizons is the story of the men and women behind this amazing mission: of their decades-long commitment and persistence; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons’ next encounter, 1 billion miles past Pluto in 2019. Told from the insider’s perspective of mission leader Dr. Alan Stern and others on New Horizons, Chasing New Horizons is a riveting story of scientific discovery, and of how much we humans can achieve when people focused on a dream work together toward their incredible goal.
